Here is info about me, my goals, status
Profile
- Name: David
- Country: Canada
- Schooling: Currently attending University
- Field of Study: Combined Computer Science and Business Management
My Goals:
- To build a RepStrap/CNC platform that has quickly Interchangeable/Multiple Tool-heads.
- To contribute to the RepRap community, via wiki, and hopefully The sale of RepRaps kits/parts to help this community grow.
- Learn More than what I already know.
- To help in the development of a basic sewing machine / Embroidery attachment for the RepRap.
Current Status:
Acquiring Parts / Starting to Assemble
- Here is what I have so far:
- Motors:
- 100 Sanyo Denki, Nema 17, Bi-Polar 6 wire stepper motors, Type: 102H5208-10U41 , 59oz-in holding torque.
- File:Sanyo103H5208.pdf
- with a 21 tooth MXL 1/4" wide pulley on each. Cost: PRICELESS steal!
- cost me $114 bucks for the whole lot. But, shipping and import fees where $165 so it came to $278
- but $278/100 = $2.78 for each motor with shipping... hmmmm. these motors sell at $15-40 on ebay... ($60 new)
- However, getting the data sheet for theses was a royal pain, even at that I still need to update it.
- 60 T&L International Stepping motor, Bi-Polar 6 wire stepping motor, Type: 42BYG401-06A, apx 31+oz-in holding torque
- with a 28 tooth mxl 1/4 brass pulley on each. Cost: Almost a Priceless steal.
- little bit more pricey about $300 with import fees
- $300 / 60 = $5 each with shipping, but they still have a gear head and it is the same sad story on ebay $15-40
- Now data on these was even harder to find but I have some and am going to make a cad scehmatic soon
- The Brain (aka BRAINS! or motherboard for the non-Zombie fans):
- I purchase a "Seeedduino mega" when it was on sale
- I think it is are great so I am planning on using it(even if it is overkill).
- Motor Drivers:
- I bought components for "EasyDrivers"
- They will provide 750mAmps at 30v per phase
- you can buy them from Sparkfun.com but I wanted to make my own)
- Ended up getting some polulu motor drivers when they went on sale for my first reprap
- Structure (aka Frame):
- 8 Hardened steel rods I salvaged from a bunch of old printers for the slides (free - 2hrs salvage)
- 6 3ft 5/16 galvanized Threaded rods ($3 each, got them on sale at princess auto)
- apx 20+ nuts ( DANG expensive at home depot, or home hardware at +$0.26 each, buy them at totem for $0.12 instead)
- 100+ 1/4 USS washers (+$0.12 each, so I bought a box of a hundred at $0.05 each instead.)
- USS type are NOT CONSISTENT IN THICKNESS(0.51" - 0.90"), they need presorting so they are 0.01" of eachother
- Corners (aka the pieces that make those annoying angles):
- I am cutting the intial ones out of 3/4 MDF which I will seal using wood hardener or glue-water mix.
So in essence My first reprap will actually be a repstrap/ wolfstrap since it uses wood, but hey it is cheaper than trying to buy the plastic parts since anyone I can find wants to charge a (explicit descriptive here) for them.
(The only reason this is not on a development page yet, is because I am still getting parts, taking pictures, procrastinating, assembling stuff, making excuses, writing essays)(OK, it is really cause I havent got to it yet, but I will as soon as the semester is over (around May 2nd))
